C# 在asp.net c中将powershell脚本的输出绑定到gridview#

我对c#非常陌生，我希望我尝试做的很简单，但我无法找到或遵循其他示例，其中powershell数组的输出填充gridview以进一步操作/执行另一个脚本。页面加载的过程是运行powershell脚本，该脚本创建一个会话详细信息数组，用于填充gridview。然后，通过选择gridview行，可以启动第二个脚本与该会话交互（例如，强制注销）

使用其他示例，我成功地启动了第一次powershell执行，它通过以下方式将数据抛出表单：

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="PowerShellExecution.Default" %>

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
     <div>
           <h1>PowerShell Harness<asp:Label ID="Label1" runat="server" Text="Label" Visible="False"></asp:Label>
           </h1>
           <asp:TextBox ID="ResultBox" TextMode="MultiLine" Width="1000px" Height="400px" runat="server"></asp:TextBox>
    </div>
</asp:Content>

当前，输出作为输出字符串抛出到文本框。我甚至在如何开始将该数组输出绑定为gridview中的行方面都遇到了困难。只需要一点点的手就可以开始了

提前谢谢！

我已经有一段时间没有涉足WebForms了，但我找到了一种方法来完成您所追求的

首先，让我们稍微更改一下PowerShell脚本。我们可以简单地返回对象，而不是返回字符串（这就是

|out string

所做的事情）。C#代码中的

shell.Invoke（）

方法知道如何从脚本的输出中提取完全成熟的对象，因此我们不需要在PowerShell脚本中序列化为字符串，然后再次尝试将其反序列化回C#代码中的对象

暂时忽略您的业务线逻辑，我的脚本只返回一个PSCustomObjects数组，如下所示：

MyScript.ps1

写入输出@(
（新对象PSCustomObject-属性（[已排序]@{
“MyProperty1”=“MyValue1.1”
“MyProperty2”=“MyValue2.1”
“MyProperty3”=“MyValue3.1”
})),
（新对象PSCustomObject-属性（[已排序]@{
“MyProperty1”=“MyValue1.2”
“MyProperty2”=“MyValue2.2”
“MyProperty3”=“MyValue3.2”
}))
);

现在，我的C#Page#u加载方法执行以下操作：

Default.aspx.cs

受保护的无效页面加载（对象发送方，事件参数e）
{
//初始化PowerShell引擎
var powershell=powershell.Create（）；
//将脚本添加到PowerShell对象
var script=“c:\\temp\\MyScript.ps1”；
powershell.Commands.AddCommand（脚本）；
//执行脚本
var results=powershell.Invoke（）；
...

而

结果

包含一个

系统.Collections.ObjectModel.Collection

。我们无法将其直接数据绑定到GridView，因为属性隐藏在每个

PSObject

成员的

属性

中的键值对中，但如果我们创建一个新类，则很容易将值提取到一些我们可以数据绑定的东西：

MyClass.cs

公共类MyClass
{
公共字符串MyProperty1{get；set；}
公共字符串MyProperty2{get；set；}
公共字符串MyProperty3{get；set；}
}

我们的页面加载可以将PSObject转换为此类的实例：

Default.aspx.cs

。。。
变量对象=结果。选择(
r=>newmyclass
{
MyProperty1=（字符串）r.Properties[“MyProperty1”].Value，
MyProperty2=（字符串）r.Properties[“MyProperty2”].Value，
MyProperty3=（字符串）r.Properties[“MyProperty3”].Value，
}
);
this.ResultGrid.DataSource=对象；
this.ResultGrid.DataBind（）；
}

然后，要显示数据，只需在Default.aspx中添加一个GridView，其中包含要定义的任何列和格式：

Default.aspx

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
     <div>
           <h1>PowerShell Harness<asp:Label ID="Label1" runat="server" Text="Label" Visible="False"></asp:Label></h1>
            <asp:GridView ID="ResultGrid" runat="server" AutoGenerateColumns="false">
                <Columns>
                    <asp:BoundField DataField="MyProperty1" HeaderText="My Property 1" />
                    <asp:BoundField DataField="MyProperty2" HeaderText="My Property 2"  />
                    <asp:BoundField DataField="MyProperty3" HeaderText="My Property 3"  />
                </Columns>
            </asp:GridView>
    </div>
</asp:Content>

注意

您可能会发现您的
Get-BrokerSession
cmdlet已经返回了特定类型对象的集合，而不是PSCustomObject，在这种情况下，您可能会跳过转换步骤，直接将数据绑定到
results
对象，因此您可能需要使用它来查看。如果有任何差异，希望上面的内容能给你一些提示

希望这能有所帮助。
非常感谢您的指导。Gridview现在已填充

    protected void Page_Load(object sender, EventArgs e)
    {
      // Gets the name if authenticated.
            if (User.Identity.IsAuthenticated)
                Label1.Text = User.Identity.Name;
            else
                Label1.Text = "No user identity available.";

        // Clean the Result TextBox

        // Initialize PowerShell engine
        var shell = PowerShell.Create();

        // Add the script to the PowerShell object
        // shell.Commands.AddScript(Input.Text);
        // shell.Commands.AddScript("D:\\Local_Scripts\\sessioncall.ps1");
        shell.Commands.AddCommand("c:\\Local_Scripts\\sessioncall.ps1");

        // Add Params
        // shell.Commands.AddParameter(null,User.Identity.Name);
        // shell.Commands.AddParameter("Username", Label1.Text);
        shell.Commands.AddArgument(User.Identity.Name);

        // Execute the script
        var results = shell.Invoke();

        // display results, with BaseObject converted to string
        // Note : use |out-string for console-like output
        if (results.Count > 0)
        {
            // We use a string builder ton create our result text
            var results2 = shell.Invoke();
            foreach (var psObject in results)
            {
                // Convert the Base Object to a string and append it to the string builder.
                // Add \r\n for line breaks
                var UserFullName = (psObject.Members["UserFullName"]);
                var BrokeringTime = (psObject.Members["BrokeringTime"]);
                var ClientName = (psObject.Members["ClientName"]);
                var DesktopGroupName = (psObject.Members["DesktopGroupName"]);
                var SessionState = (psObject.Members["SessionState"]);
                var Uid = (psObject.Members["Uid"]);
                var MachineName = (psObject.Members["MachineName"]);
                var ENV = (psObject.Members["ENV"]);
                // builder.Append(psObject.BaseObject.ToString() + "\r\n");
            }

            this.ResultGrid.DataSource = results2;
            this.ResultGrid.DataBind();
        }

        }

返回
[！[在此处输入图像描述][1][1]

但是，当您随后定义datakeyname时，此方法会引发异常错误

<asp:GridView ID="ResultGrid" runat="server" DataKeyNames="uid" AutoGenerateColumns="False" OnSelectedIndexChanged="ResultGrid_SelectedIndexChanged">
                <Columns>
                     <asp:buttonfield buttontype="Button" 
                 commandname="Select"
                 headertext="View" 
                 text="View"/>
                    <asp:BoundField DataField="UserFullName" HeaderText="UserFullName" />
                    <asp:BoundField DataField="BrokeringTime" HeaderText="BrokeringTime"  />
                    <asp:BoundField DataField="ClientName" HeaderText="ClientName"  />
                    <asp:BoundField DataField="DesktopGroupName" HeaderText="DesktopGroupName" />
                    <asp:BoundField DataField="SessionState" HeaderText="SessionState"  />
                    <asp:BoundField DataField="Uid" HeaderText="Uid"  />
                    <asp:BoundField DataField="MachineName" HeaderText="MachineName"  />
                    <asp:BoundField DataField="ENV" HeaderText="ENV"  />
                </Columns>
            </asp:GridView>

这会在以下位置引发异常错误：

this.ResultGrid.DataBind（）

“System.Web.HttpException:'DataBinding:'System.Management.Automation.PSObject'不包含名为'uid'的属性。”

我不清楚这个方法是现在的问题还是其他问题。我很困惑，因为它必须正确地看到PSObject内部，才能定义变量并填充gridview？！嗯

哇,；好啊我刚刚意识到这整个部分都被忽略了！恰当的例子；它可以被注释掉！因此，请清楚地调整powershell脚本的输出

 foreach (var psObject in results)
                {
                    // Convert the Base Object to a string and append it to the string builder.
                    // Add \r\n for line breaks
                    //var UserFullName = (psObject.Members["UserFullName"]);
                    //var BrokeringTime = (psObject.Members["BrokeringTime"]);
                    //var ClientName = (psObject.Members["ClientName"]);
                    //var DesktopGroupName = (psObject.Members["DesktopGroupName"]);
                    //var SessionState = (psObject.Members["SessionState"]);
                    //var Uid = (psObject.Members["Uid"]);
                    //var MachineName = (psObject.Members["MachineName"]);
                    //var ENV = (psObject.Members["ENV"]);
                    // builder.Append(psObject.BaseObject.ToString() + "\r\n");
                }

原谅我，我就快到了

r => new MyClass
                        {
                            UserFullName = (string)r.Properties["UserFullName"].Value,
                            BrokeringTime = (DateTime)r.Properties["BrokeringTime"].Value,
                            ClientName = (string)r.Properties["ClientName"].Value,
                            DesktopGroupName = (string)r.Properties["DesktopGroupName"].Value,
                            //SessionState = (string)r.Properties["SessionState"].Value,
                            Uid = (Int64)r.Properties["Uid"].Value,
                            //MachineName = (string)r.Properties["MachineName"].Value,
                            //ENV = (string)r.Properties["ENV"].Value,
                        }
                    );
                this.ResultGrid.DataSource = objects;
                this.ResultGrid.DataBind();
            }

            }

        protected void ResultGrid_SelectedIndexChanged(object sender, EventArgs e)
        {

            Response.Write(ResultGrid.SelectedValue.ToString());

        }
    }

    internal class MyClass
    {
        public string UserFullName { get; set; }
        public DateTime BrokeringTime { get; set; }
        public string ClientName { get; set; }
        public string DesktopGroupName { get; set; }
        public String SessionState { get; set; }
        public Int64 Uid { get; set; }
        public string MachineName { get; set; }
        public string ENV { get; set; }
    }

所以我现在正确地填充了gridview；有些列仍然存在问题，没有被视为字符串，但我几乎做到了

r => new MyClass
                        {
                            UserFullName = (string)r.Properties["UserFullName"].Value,
                            BrokeringTime = (DateTime)r.Properties["BrokeringTime"].Value,
                            ClientName = (string)r.Properties["ClientName"].Value,
                            DesktopGroupName = (string)r.Properties["DesktopGroupName"].Value,
                            //SessionState = (string)r.Properties["SessionState"].Value,
                            Uid = (Int64)r.Properties["Uid"].Value,
                            //MachineName = (string)r.Properties["MachineName"].Value,
                            //ENV = (string)r.Properties["ENV"].Value,
                        }
                    );
                this.ResultGrid.DataSource = objects;
                this.ResultGrid.DataBind();
            }

            }

        protected void ResultGrid_SelectedIndexChanged(object sender, EventArgs e)
        {

            Response.Write(ResultGrid.SelectedValue.ToString());

        }
    }

    internal class MyClass
    {
        public string UserFullName { get; set; }
        public DateTime BrokeringTime { get; set; }
        public string ClientName { get; set; }
        public string DesktopGroupName { get; set; }
        public String SessionState { get; set; }
        public Int64 Uid { get; set; }
        public string MachineName { get; set; }
        public string ENV { get; set; }
    }

看起来像是获取成员类型：

BrokeringTime    NoteProperty datetime BrokeringTime=28/02/2020 06:56:39 
ClientName       NoteProperty string ClientName=clientname           
DesktopGroupName NoteProperty string DesktopGroupName=desktopgroupname
ENV              NoteProperty System.String ENV=UK                       
MachineName      NoteProperty string MachineName=machinename  
SessionState     NoteProperty SessionState SessionState=Active           
Uid              NoteProperty long Uid=12345678                           
UserFullName     NoteProperty string UserFullName=username  

C#似乎确实喜欢system.string
 非常感谢！这个方法现在对我来说更清楚了，我已经成功地进行了更多的步骤！
